d3o Shoulder armour to fit most pocket-ready motorcycle and scooter jackets. d3o is soft and flexible, but upon impact absorbs and spreads energy providing maximum protection and comfort. A great upgrade to standard CE foam armor that comes in other riding suits. It prevents you looking like an American footballer / Power Ranger and is equally useful for women's clothing as it is discreet. The level 2 armour is slightly thicker and thus has even better impact absorbing properties.
